Not quite my cup of tea (but I do like the sub genre and for sharing).
If you’ve never listened to Tim Hecker’s album, Ravedeath, 1972, I can’t recommend ienough listening to 3 tracks on it (in order and in one sitting):
“No Drums”
“Hatred Of Music 1”
“Hatred Of Music 2”
Preferably in a place with no distractions with good headphones.
I can’t help but think there are a lot of “happy accidents” on these 3 tracks because there are some perfect ambient sounds that, in my case, literally struck a nerve.
